/**
 * simvsm-import module — public entrypoint (ADR 019).
 *
 * Owner: Wertstrom
 *
 * Wertstrom P6 (KAR-878/KAR-986, execution-prompt §14, Capability-Matrix
 * A16): optional SimVSM-file import adapter — parse, recognize Familien
 * (model + alternatives + paired SVGs), map onto the existing P2 data model
 * (VsmNode/VsmConnection/ScenarioKind, zero schema changes), preview before
 * any write, confirm idempotently. Feature-gated off by default
 * (`wertstromSimvsmImport`, `false` in all 3 profiles) — see README.md.
 *
 * Anything not re-exported from this file is internal and may change without
 * notice. Cross-module access goes through this entrypoint only — no deep
 * imports into this module's internal/.
